A steering yoke 1 according to an embodiment of the present utility model is described below with reference to fig. 1 to 4.
As shown in fig. 2 and 3, the steering yoke 1 according to the embodiment of the present utility model includes a connecting portion 11 and a rotating portion 12.
Specifically, referring to fig. 3, the connection part 11 is connected with the rotation part 12, the connection part 11 has a connection hole 111, a notch 1111 penetrating the connection part 11 in the axial direction of the connection part 11 is formed in the peripheral wall of the connection hole 111, the clasping degree and the fitting degree of the connection hole 111 and the component to be matched can be adjusted by adjusting the size of the notch 1111, and when the notch 1111 becomes large, the clasping degree and the fitting degree of the connection hole 111 and the component to be matched are reduced, so that the component to be matched is convenient to assemble and disassemble; when the notch 1111 becomes smaller, the degree of clasping and fitting of the connection hole 111 and the member to be fitted increases, facilitating fixation between the connection portion 11 and the member to be fitted.
The inner peripheral wall of the connection hole 111 is provided with a plurality of inner key teeth 1112 spaced apart in the circumferential direction of the connection hole 111, and a central angle a between edges of two inner key teeth 1112 adjacent to the notch 1111 on both sides of the notch 1111 is 90 to 150 °, and the central angle a may be 90 °, 100 °, 120 ° or 150 °. It will be appreciated that the connection hole 111 and the component to be fitted are connected by a spline housing, and the region of the inner peripheral wall of the connection hole 111 where the inner spline 1112 is arranged is a connection acting surface.
When the central angle a is greater than 150 °, for example, 160 °, 180 °, 200 ° or 230 °, the connection acting surface between the connection hole 111 and the component to be mated is insufficient, and the connection effect between the connection hole 111 and the component to be mated is affected; when the central angle a is smaller than 90 °, for example, 80 °, 60 °, 30 °, or 10 °, the connection acting surface between the connection hole 111 and the component to be mated is excessive, thereby affecting the holding state of the acting surface excessive portion of the connection hole 111 and the component to be mated, so that the possibility of rusting of the acting surface excessive portion of the connection hole 111 becomes large, thereby affecting the connection between the connection portion 11 and the component to be mated.
In other words, when the internal teeth 1112 are located on both sides of the notch 1111 and the central angle a between the edges of two internal teeth 1112 adjacent to the notch 1111, which are close to the notch 1111, is 90 ° to 150 °, the distribution of the internal teeth 1112 is optimized, so that the connection acting surface between the connection hole 111 and the component to be mated is convenient, the probability of rust of the internal teeth 1112 is reduced, and the connection reliability between the connection hole 111 and the component to be mated is improved.
Further, since the inner key teeth 1112 of the excessive part of the connection acting surface between the connection hole 111 and the component to be matched are reduced, the tightening force generated by the shrinkage of the notch 1111 can be distributed to the inner key teeth 1112 of the convenient part of the connection acting surface more, the tightening force between the inner key teeth 1112 of the unit and the matched part is improved, the connection reliability between the connection hole 111 and the component to be matched is further improved, and the tightening effect is good.
In addition, by optimizing the distribution range of the inner key teeth 1112 and thus optimizing the locking state of the connecting hole 111, it is possible to save the steering yoke 1 and add an additional structure to enhance the fastening effect of the connecting portion 11, so that the structure is simpler.
The fastening members 13 are arranged on the two sides of the connection notch 1111, the fastening members 13 are connected to enable the notch 1111 to be smaller, so that the connection hole 111 is limited to be expanded, the fastening force of the connection hole 111 to the parts to be matched is improved, and accordingly connection reliability between the connection portion 11 and the parts to be matched is improved.
When the steering yoke 1 is connected with the gear shaft 50, the components to be matched are placed into the connecting hole 111 of the connecting part 11 and are matched with the inner key teeth 1112 in the connecting hole 111, and then the two side parts of the notch 1111 are connected through the fastener 13, so that the notch 1111 is reduced, the components to be matched and the connecting hole 111 are tightly locked, and the steering yoke 1 is connected with the components to be matched.
According to the steering yoke 1 of the embodiment of the utility model, the connecting portion 11 and the rotating portion 12 are arranged, the connecting hole 111 is arranged on the connecting portion 11, the notch 1111 penetrating the connecting portion 11 in the axial direction of the connecting portion 11 is arranged on the peripheral wall of the connecting portion 111, the plurality of inner key teeth 1112 which are spaced along the circumferential direction of the connecting portion 111 are arranged on the inner peripheral wall of the connecting portion 111, the central angle A between the edges of the two inner key teeth 1112 which are respectively positioned at two sides of the notch 1111 and are adjacent to the notch 1111 and are close to the notch 1111 is 90-150 degrees, the distribution range of the inner key teeth 1112 is optimized, the locking state of the connecting portion 111 is optimized, the fastening pieces 13 which are connected with the two sides of the notch 1111 are arranged on the connecting portion 11, the notch 1111 is reduced through the fastening pieces 13, the connecting portion 111 is shortened and is tightly held with the components which are needed to be matched, the steering yoke 1 and the gear shaft 50 are connected, meanwhile the steering yoke 1 saves the additional structure for enhancing the fastening effect of the connecting portion 11, the fastening effect is good in structure, abnormal sound is reduced, and rust is not easy to occur.

In the example shown in fig. 3, the number of the internal teeth 1112 on the reference surface 112 on the side close to the notch 1111 on both sides of the notch 1111 is 3, but the utility model is not limited thereto, and the number of the internal teeth 1112 may be 3, 4 or 5.
Since the contact stress of the internal teeth 1112 is mainly concentrated near the reference surface 112, the arrangement of a proper amount of internal teeth 1112 on the two sides of the notch 1111 on the side of the reference surface 112 near the notch 1111 makes the clasping state between the connection hole 111 and the component to be matched better, if the number of the arranged internal teeth 1112 is less than 3, such as 2 or 1, the distribution of the internal teeth 1112 on the connection acting surface is insufficient, thereby affecting the connection reliability between the connection part 11 and the component to be matched, and if the number of the arranged internal teeth 1112 is more than 5, such as 6, 7, 8 or 10, the stress of the single internal teeth 1112 is reduced, the clasping degree is reduced, the probability of rusting of the internal teeth 1112 in the connection acting surface is increased, and the connection between the connection part 11 and the component to be matched is further affected.
In some embodiments of the present utility model, as shown in fig. 3, the plurality of internal teeth 1112 are symmetrically disposed about the axis of the notch 1111, so that the connection portion 11 is uniformly stressed on both sides of the axis of the notch 1111, reducing the damage effect of the internal teeth 1112 caused by uneven stress, and increasing the structural stability of the connection portion 11.
In some embodiments of the present utility model, as shown in fig. 3, the distance between any two adjacent inner teeth 1112 is equal along the circumferential direction of the connecting hole 111, so as to improve the probability of matching between the inner teeth 1112 of the connecting hole 111 and the outer teeth of the gear shaft 50, facilitate the matching and installation, and simultaneously make the stress between the inner teeth 1112 and the outer teeth uniform, and increase the reliability of the connection between the connecting portion 11 and the gear shaft 50.
